The $10 Trillion Climate Bonanza

Roughly $10 trillion per year, or 12% of the global economy, is now in play fighting climate change.

Properly invested in the zero emission energy, transport and business infrastructure of tomorrow, this $10 trillion per year can create the future income streams needed to pay the health and retirement costs of an aging global population.

The first and most important step lies in taxing carbon and eliminating fossil fuel subsidies. This frees up $6.6 trillion a year, or nearly 8% of the global economy, for more productive uses. Fixing climate change also will reduce health costs by nearly $3.2 trillion a year.

That total of just under $10 trillion dollars is roughly the amount needed per year to revamp and upgrading the world’s infrastructure: like roads, airports, trains and water supply systems.

A separate $2.5 trillion a year can be used to udpated energy networks to deliver zero emission electricity from producer to consumer.

The savings from economic reform and reduced health costs can fund the infrastructure needs of a zero emission economy and meet looming social security obligations, with a small surplus left over.

Humanity comes out ahead. While the above numbersare estimates, they represent the best guesses of the best minds. Thepicture they paint is unmistakable.

By contrast, leaving climate change unaddressed puts at risk as much as $24 trillion of economic assets. That’s nearly a third of global GDP and amultiple of the figures above.

Thepolitical and economic roadmap of the 21st Century is now clear. What’s needed is a huge, multigenerational fiscal stimulus of linked infrastructure investment and linkage to looming long-term social security payment schemes.

Over the short- to medium term (now to 2030) large infrastructure and clean energy construction projects will spark economic activity throughout the global economy,. This will stimulate employment and consumer demand and reflate the global economy.

Debt funding would be secured in whole or in part by claims on future cash flows. These cash flows in turn would pay the costs of a global population expected to rise from today’s 8 billion to 10 billion by 2050 and potentially 11 billion by 2100.

Virtually all countries have grossly underfunded social security programs. Linking investment in fixing climate change to the need to pay for global aging solves two problems simultaneously.

The money needed can be catalyzed — at least initially — through existing multilateral financial instittions liked the Asian Development Bank (ADB), China’s Asian Infrastructure Investment Bank (AIIB), the World Bank and others.

These would serve as the financial intermediaries for recycled carbon taxes and eliminated fossil fuel subsidies.

Each country could pursue these measures at their own speed. The only truly global agreement required would be on technical standards for energy market interconnection. These largely already exist. The internet is an example.

Key to the success of a future clean energy economy will be liberalization of energy markets. This means, in general terms, severing dedicated linkages between upstream, midstream and downstream markets to enable greater competition.

This involves encouraging, or mandating, ‘open-access, common-carrier’ operations of networks.This means requiring gas pipelines and power lines to set common tariffs applicable to all comers on a first-come, first-served basis, instead of restricting access to favored counterparties.

Systems like this already exist, for instance in the operation of the United States’s nationwide natural gas distribution system. Critical reforms along these lines also are underway in China.

There, electricity and gas infrastructure owners are being required to open them further to competiton by enabling access at non discriminatory prices. As this occurs, capital will flow to toward cleaner energy sources. This will create a positively-reinforcing circle.

In addition to spurring competition among energy producers and distributors, it will also create an infrastructure class capable of throwing of off the predictable cash flows needed to offset retirement payment needs.

Organizations ranging from the International Monetary Fund to the International Energy Agency now warn about the risks to the global economy from underinvestment. Another risk is malinvestment, for instance in short-lived Liquid Natural Gas infrastructure when pipelines represent a much more sensible option.

An integrated global natural gas/hydrogen pipelline and electricity infrastructure represents future proof investment. That’s because the system can enable allow transmission and storage of of surplus energy either as as electricity (for instance, through batteries, pumped hydro or compressed air) or in gaseous form (as hydogen). This flexibility has enormous value.

The precedent for quick action exists. The first international subsea fiber optic cable (TAT5) was only laid in 1988, less than 30 years ago. Today, the globe is criss-crossed by fiber optic capacity unimaginable in 1988.

These fiber cables provide both the inspiration and the pathways for parallel trans-national infrastructure, like gas pipelines and electricity power lines.
